定义
传导性听力损失是指声波在通过外耳、鼓膜（耳膜）或中耳（听小骨）的任何地方出现传导问题。感音神经性听力损失是一种听力损失，其根本原因在于前庭神经（第八颅神经）、内耳或大脑的中央处理中心。这种诊断是指传导性和感音神经性听力损失的混合。
Conductive hearing loss occurs when there is a problem conducting sound waves anywhere along the route through the outer ear, tympanic membrane (eardrum), or middle ear (ossicles). Sensorineural hearing loss is a type of hearing loss in which the root cause lies in the vestibulocochlear nerve (Cranial nerve VIII), the inner ear, or central processing centres of the brain. This diagnosis refers to a mix of both conductive and sensorineural hearing loss.
